expand (x-4)(3x^2+3x-1)

expand

(x - 4) (3 x^{2} + 3 x - 1)

3 x^{3} - 9 x^{2} - 13 x + 4

Solution steps

(x - 4) (3 x^{2} + 3 x - 1)

Distribute parentheses

= x \cdot 3 x^{2} + x \cdot 3 x + x (- 1) - 4 \cdot 3 x^{2} - 4 \cdot 3 x - 4 (- 1)

Simplify

x \cdot 3 x^{2} + x \cdot 3 x + x (- 1) - 4 \cdot 3 x^{2} - 4 \cdot 3 x - 4 (- 1) : 3 x^{3} - 9 x^{2} - 13 x + 4

= 3 x^{3} - 9 x^{2} - 13 x + 4

\frac{3}{7} \cdot \frac{1}{3}

\frac{8 x ^{3} + y ^{3}}{2 x + y}

\frac{3}{5} \cdot \frac{7}{9}

\frac{( 1 + x ) ^{3} - 1}{x}

3 k + 9 - k - 17
